A tower uses energy, so let’s set the harvester role to bring energy to the tower along with other structures.
To do this, you need to add the constant <code>STRUCTURE_TOWER</code> to the filter of structures your
harvester is aimed at.

Add <code>STRUCTURE_TOWER</code> to the module <code>role.harvester</code> and wait for the energy to appear in the tower.
